【问题讨论】：

分享你的配置类并简要介绍你的技术栈

嗨@YogendraR，刚刚更新了上面的配置类，我们使用的是spring，hibernate，java wrapper

你可以尝试删除 sessionFactory.getObject()，只返回 sessionFactory，并在调用 setSessionFactory() 时使用 sessionFactory().getObject() 并用 @Bean 注释你的 newDataSource()

我试过了，还是一样的异常。

return sessionFactory.getObject() 改为return (SessionFactory) sessionFactory。 hibernateTransactionManager.setSessionFactory(this.sessionFactory()) 更改为 hibernateTransactionManager.setSessionFactory(((LocalSessionFactoryBean) sessionFactory()).getObject())。并用 @Bean 注释 newDataSource()

【参考方案1】：

在您的休眠配置类文件中，您应该正确定义会话对象属性及其方言、数据源和事务管理器，不要忘记用@Bean 注释它们

【讨论】：

我都做了，你建议如何更改上述代码？

嗨，我在上面更新了，我看到另一个堆栈跟踪，再次运行时，这是最底层的堆栈跟踪，这应该是原因...引起：java.lang.NullPointerException at org .hibernate.engine.jdbc.connections.spi.AbstractDataSourceBasedMultiTenantConnectionProviderImpl.getAnyConnection(AbstractDataSourceBasedMultiTenantConnectionProviderImpl.java:42)

我认为如果你分享你的配置类代码和抛出异常的代码会有帮助
